Most military strategists will repeat that Napoleon was so victories by using artillery. Just, did you ever google what Napoleon called Artillery?
You were thinking of kind'a that, right:
But that was ship and fortress canons. They were too heavy to be moved and therefore stationairy. Until the nuclar bomb all defence was way stronger than attackers.
This was the canons:
Every stupid junky, and that is exactly what you have to be, can drop a nuclear bomb as in Hiroshima and Nagasaki to afterwards come in all pride to threaten the rest of the world...
Napoleon was actually using tanks, but a modern tank. A tank in WW1 was created to overrun barb wire and had several machine guns, but only a small canon compared to modern main battle tanks. Artillery of WW1 shot first time on parameters and not on sight. Napoleon instead used guns mounted on special cars being able to be moved with horses realy quicky around a battle field, that could advance by having one man on each wheel to close in, and his actual expertise was his social skills coordinating the Horsmen coming from Knight famlies, the Infanterists coming from defencible Villages and Citizen Clubs and the new Artillery. He had no soldiers, but payed the man in arms, that even left homes without their woman and some kids on cars providing food and ambulance. He refused the crown and brought the Revolution against those that today have written history books. He is Ché Guevarras Father in mind.
And I like Robbespierre a very lot. That's the guy that mounted a Guilliotine on a car. You can run, but you can't hide.
